Product Advantages
Why Choose AC-VcOS
AC-VcOS combines the familiar skincare role of a vitamin C derivative with the formulation freedom of an oil-soluble liquid.
| Oil-Soluble Vitamin C | Adds a vitamin C derivative to oil phases and anhydrous systems where water-soluble formats are less convenient. |
|---|---|
| Brightening and Tone | Supports formulas positioned around radiance and a more even-looking complexion. |
| Antioxidant Role | Can be incorporated as part of the antioxidant strategy for the finished cosmetic formula. |
| Liquid Handling | The colorless to pale-yellow liquid can be evaluated through a compatible oil phase or a validated late-addition route. |
| Broad Format Fit | Suitable for face oils, serums, creams, lotions, balms and color cosmetics. |
| Quality Control | Control in accordance with the specifications. |

Application
AC-VcOS Oil-Phase Processing Guide
Preserve the value of the oil-soluble format by controlling heat, oxygen and the surrounding oil blend.
- Set the level within 0.1-5% Choose the starting point from the formula type and desired benefits, then refine it through stability and performance testing.
- Place it in the compatible oil route Use a compatible oil phase or a validated late-addition step rather than forcing it into the water phase.
- Control oxidation Pair chelation and antioxidant support with packaging that limits unnecessary oxygen and light exposure.
- Watch color and assay Track appearance, odor, assay retention and phase stability throughout the intended shelf-life study.
Formula Systems to Evaluate
Face oils
Serums
Creams
Lotions

FAQ
AC-VcOS FAQ
Straightforward answers for using an oil-soluble vitamin C derivative across cosmetic formats.
How is AC-VcOS different from a water-soluble vitamin C derivative?
AC-VcOS is oil soluble, so it can be evaluated directly in face oils, balms, emulsions and other lipid-rich formats.
Can AC-VcOS be used in anhydrous face oils?
Yes. Its oil-soluble liquid format is suited to anhydrous concepts, subject to oil-blend compatibility, oxidation control and packaging tests.
What is the suggested use level?
Use 0.1-5% as a starting range, then optimize the level through finished-formula stability, tolerance and performance testing.
How should AC-VcOS be incorporated?
Use an oil-compatible route or a validated late-addition process according to the current TDS. Limit unnecessary heat and oxygen exposure.
What documents can I request?
Request the current TDS, SDS/MSDS, signed specification, recent COA, stability guidance, sample, MOQ and quotation.
